Description
The Type 4000 pneumatic valve positioner is designed
for use with System 9000 actuators. The positioner
mounts on the actuator and provides the desired valve
plug position for a specific input signal. The Type 4000
accepts a pneumatic input signal.
The positioner comes standard with gauge ports and
an O-ring sealed housing. The housing utilizes a
unique O-ring seal that can be adjusted to a sealed or
drained position.
Ease of calibration and maintenance are built into the
design with easily accessible span and zero adjust-
ment, and very simple parts replacement.
Specifications
Specifications for the Type 4000 valve positioner are
listed in table 1.
Installation
Typically, the positioner is ordered with the actuator. If
so, the factory mounts and calibrates the valve posi-
tioner. If the positioner is ordered separately from the
actuator, perform the mounting procedure. Refer to
the appropriate instruction manuals for actuator and
valve installation procedures.
WARNING
Avoid personal injury from sudden re-
lease of process pressure. Before
mounting the positioner on a valve in
service:
D
Disconnect any operating lines pro-
viding air pressure or a control signal to
the actuator. Be sure the actuator can-
not suddenly open or close the valve.
D
Use bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure on both sides of the valve.
